This heavy-duty combination trim bit is perfect for flush trimming thick stock. With a 1/2" shank and 7/8" cutting diameter, it can cleanly slice through material up to 1-3/8" thick, leaving crisp edges on both faces. The bit's ultra-long 1-3/8" cutting length allows it to reach deep inside materials for flush cuts. A compression-style design delivers the same high-quality performance as standard Ultimate bits in a sturdier package built to handle tough jobs in difficult woods. Whether trimming laminates, hardwoods or engineered materials, this industrial-grade trimmer ensures clean, precise results with every cut.
